Drop a perpendicular..... then using Pythagoras theorem, find h in terms of x (x=base - remaining length) for both the triangles which are on right & left side to the perpendicular height.... both answers are in terms of x, now compare h to find x, then find h ultimately.

How do you find th area of triangle?
Area of a triangle = 0.5*base*perpendicular height
How do you find area of a trinagle?
Area of a triangle = 0.5*base*perpendicular height
How do you find the base and height of an isosceles triangle?
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
When can you use two side lengths to find the area of a triangle?
The area of any triangle is: 0.5*base*perpendicular height
Who found out how to find the area of a triangle?
Find the length of the base and the perpendicular height. Multiply together. Divide answer by 2. Area of Triangle = ½(Base x Perpendicular Height) For right angled triangles, take the length of the two shortest sides, multiply them together and divide the answer by two.
How do you find the perpendicular height of a triangle?
If it is a right triangle, you can use the Pythagorean theorem to find the height since it will be on of the sides. If it is an equilateral triangle, you can break it up into two right triangles and use the part above. If it is an oblique triangle, you use the angles and some trigonometry to find it. Since the area is 1/2 b x h, if you are given the area, you can solve for the height.
How do you find th area of triangle?
Area of a triangle = 0.5*base*perpendicular height
Volume of an oblique cone?
Find the perpendicular height from the apex to the base.The volume is one third of the base area times the perpendicluar height.
How do you find the perimeter of a triangle with perpendicular height?
The height of a triangle alone is not enough information to find the perimeter. You need some angle measures or side lengths.
How do you find area of a trinagle?
Area of a triangle = 0.5*base*perpendicular height
How do you find the base and height of an isosceles triangle?
An isosceles triangle has 2 equal base angles and its height is perpendicular from its apex to the centre of its base
When can you use two side lengths to find the area of a triangle?
The area of any triangle is: 0.5*base*perpendicular height
Who found out how to find the area of a triangle?
Find the length of the base and the perpendicular height. Multiply together. Divide answer by 2. Area of Triangle = ½(Base x Perpendicular Height) For right angled triangles, take the length of the two shortest sides, multiply them together and divide the answer by two.
How do you find the heighth of a triangle?
To find the height of a triangle, you can use the formula: height = (2 * area) / base. The base of the triangle is one side of the triangle to which the height is perpendicular. The area can be calculated using different methods depending on the information available, such as using the lengths of the sides and Heron's formula or using the base and the height.
How do you find volume and area of a triangle?
A triangle has no volume - it is a 2-dimensional shape only. To find the area, multiply the base times the height, then divide by 2. The base is any side of the triangle; the height must be measured perpendicular to the base.
Find the area of an equilateral triangle with side 10?
Finding the perpendicular height of the triangle by using Pythagoras works out at about 8.660254038. 1/2*base*perpendicular height or altitude = area 1/2*10*8.660254038 = 43.30127019 square units
How do you find the base and height of a triangle when you already know the area?
area = 1/2 base * perpendicular height you can't find both the base and the height if you only know the area
